ebinmaine 66,411 #2 Posted August 21 You can either run SAE 40 oil, 75 to 80 W 90, or up to 140. We run the least expensive 75/80 W 90 I can get my hands on when I need it. Doesn't matter if it's gl4 or gl5 because Wheel Horse transmissions don't have yellow metal parts. Either one is fine. 4 1 1 Share this post Link to post Share on other sites
